Hi, I'm wondering if anyone out there has used the commonly available 'ninja stick' that can be bought in martial art stores. I'm curious about the durability of it. I am considering buying one as a self defense object but I only want to consider it if it can withstand use as a grappling tool.

Ideally I would like it to simulate/replicate the abilities of grappling using a half staff or full police (non expandable) baton. I'm not so concerned with the ability to strike with it, just its ability to withstand a lot of pressure the ends of it.

Anyone care to comment? Or if you know of a similar product, please let me know. Thanks.

I would not recommend anything typically purchased in a Martial Arts store for Self Defense. Especially if it has moving parts. MA store merchendise is typically low quality imported novelty items that are great for show but do not hold up under conditions of actual use.

Ensure that you are clear and in in accordance with the laws of your state or region before purchase.

I don't know of many units that still use the old 1 piece baton. The ASP is usually carried in a leather pouch on the belt or extended in a holster designed for it.

I have read it's made of aluminum, can anyone with experience relate to me whether or not it will stand up to use in grappling? Specifically I want it to be able to withstand such things as aiding in arm bars shoulder locks and chokes, I can't see it ever needing to withstand more than about 40-50lbs of pressure. Will it hold up to that?

The ASP and the Monadnock Expandable Baton will both stand up to grappling use.

Many agencies have dumped the side handle baton (Tonfa for you Kobudo people) in favor of the expandable. This is both for ease of carry, use and of course, for the images burned into the public's eyes from the Rodney King video.
